This article is the second in our renewable energy patent tracker series. The first, published early March 2021, compared patent trends for renewable energy generation technology from 2016 to 2020 with data from the first two months of this year. Using the Y02 classification scheme developed by the EPO for labelling climate change mitigation technologies, we compared the number of publications in different renewable energy fields (solar PV, solar thermal, wind, geothermal, hydro and from the sea) and ranked the biggest patent filers in these areas. In this instalment, we update our statistics for this year, incorporating data from up until the 19th May, and extend our trend analysis over the ten years leading up to 2021.
The first long-haul flight powered by biofuels took off on 18th May 2021. An Air France-KLM flight from Paris to Montreal used a mix of conventional jet fuel and a sustainable aviation fuel (SAF) made from used cooking oils. Also, the UK Government has recently announced that it will mandate the introduction of E10 fuel (petrol containing up to 10% of sustainable bioethanol) from September this year
